-x + -x-1 + -x-2 = -204
-3x=-201
x=-67
-67-68-69=-204
Answer:
Speed of first plane is 350 miles per hour
Speed of second plane is 100 miles per hour
Step-by-step explanation:
Let the speed of the second plane be X
Then the speed of the first plane will be 3.5 X
Distance travelled by first plane is 9.5 *X
Distance travelled by second plane is 9.5 * 3.5 X
Difference of distance between the two plane is
miles per hour
Speed of first plane is 3.5 *100 = 350 miles per hour
Speed of second plane is 100 miles per hour
Answer:
Step-by-step explanation:
8x^2 - 4x
4x(2x - 1)
GCF is 4x
154 divided by 7 i think

Mr. Jones has 22 students per class
<span>1.) The polygon whose vertices in the coordinate plane are (-2,3) (2,3) (2,0) (-2,0) is a rectangle with length = 4 units and width = 3 units.
Therefore, only equiangular.
2.) </span>T<span>he polygon whose vertices in the coordinate plane are (3,3) (5,0) (5,-3) (1,-3) (1,0) is a triangle on top of a rectangle which is neither equilateral nor equiangular nor regular.
i.e. none of the above.
